It is constructed so as to be perpendicular to the axis 2' of the

The lower part of the peripheral surface of the hulling part D (one end side (A) of the upper rotating sorting cylinder opposite to II is placed so as to be rotatable on both supporting rollers 23 and 23 which are supported in the cover 22) The base side of the support arm 24 connected to the other end side (b) of the sorting cylinder A is mounted on one end side of a rotating shaft 25 that is mounted on the cover 22, and the base side of the support arm 24 connected to the other end side (b) of the upper rotating sorting cylinder A A receiving trough B for receiving brown rice with a cross section shaped like a square, one end of which is connected to the cover 22 in a), is extended inward over approximately the entire length of the sorting mA, and a helical structure is installed at the center of the lower part of the holder 1iiB. The conveyor 3 is installed so as to be able to rotate coaxially with the rotating shaft 25, and the lower opening of the supply tank 26 mounted above one end of the cover 22 is rotated upward so that the upper end of the mixed rice thrower 20 is visible. A paddy gutter 27 extending inward from one end side (a) of the sorting tube A and looking below the opening at the other end side (b) of the upper rotating sorting tube A is connected to the hopper of the hulling section. 16, extending inwardly so as to communicate with each other.

Further, the lower peripheral surface of the other end side (d) of the lower rotary sorting tube a, which is the side facing the hulling section, is rotatably mounted on both support rollers 28°28, and the other end of the sorting tube a The base side of the support arm 29 connected to one end side (c) is mounted on one side of the rotating shaft 30 that is mounted on the cover 22, and the lower rotary sorting tube a
A brown rice receiving trough with a cross section of ■ shape, one end of which is connected to the cover 22 at the other end (d), is extended inwardly over approximately the entire length of the sorting tube a, and the trough wJb is A spiral conveyor 3' installed in the center of the lower part is installed so that it can rotate coaxially with the rotating shaft 30, and is attached to one end side of the cover 22 so that the upper part communicates with the terminal end of the receiving gutter. The lower opening of the feed trough 31 is extended so as to look inward at one end side (c) of the lower rotary sorting tube a, and the other end side (d) of the lower rotary sorting tube a, which is the side of the hulling section, is The lower part of the gutter 33 is installed so as to communicate with the mixed rice conveyor 8 via the flow-down plate 32, and is installed below the terminal end of the gutter in the vicinity of the gutter 33. It is configured so that it communicates upward.

Therefore, one end of the rotary grain sorter C becomes a supply side and the other end becomes a discharge side.

At the upper part of one side of both receiving troughs B and b, there is provided an adjusting plate 4.4 which extends obliquely so as to approach the inner circumferential surface of the respective sorting tubes A and a, and is approximately equal to the length of the spiral conveyor 3.3'. The image adjustment plates 4.4 are arranged in series with the same length, and the image adjustment plates 4.4 are installed so that they can be rotated around a lower shaft 35.35 to change the inclination. 35
The base of the adjustment body 5.5' is fitted and fixed to the end of the image adjustment body 5.5', and a knock 37.37 fitted with a spring 36.36 interposed at the tip of the image adjustment body 5.5' is attached to the case 22. The upper adjusting body 5 is installed in a case 22 which is on the side opposite to the hulling section and is on the supply tank 26 side. The lower adjusting body 5' is installed on opposite sides of the case 22 on the hulling section side.

Both rotating shafts 2 are disposed outside the case 22 on the rear end side of the rotary grain sorter C, which is the side opposite to the hulling section side.
Both rotary shafts 25.30 extend from the transmission shaft 39 which extends with the ends of 5.30 up and down and protrudes from the rear of the gear box 6.
The belt pulleys are installed in such a manner that transmission can be transmitted via a transmission part G of a group of belt pulleys, and a safety cover (not shown) is attached to the transmission part G.

Therefore, transmission can be transmitted to each part of the huller F from the transmission part 11 arranged on the side of the wind sorting part E, and the rotary grain sorter C can be transmitted from the transmission part 1 through the gear case 6 to the transmission part G. Can be driven.

During operation, when paddy is supplied to the hopper 16, the hulls removed by the hulling section fall onto the wind-selected mixed rice conveyor 8 in the wind sorting section E, and are transferred to the supply tank 26 by the mixed rice thrower 20. The mixed rice that is jumped up from the bottom of the tank 26 and fed into one end side (A) of the downward rotating sorting tube A from the lower opening of the tank 26 is fed inside the sorting tube A rotating in the direction of the arrow (E). While in contact with the circumferential surface, the brown rice fits into the four parts 1 and is lifted up to the side, but the paddy cannot fit into the four parts 1 and slides down the inner circumferential surface, and the brown rice that is lifted upwards '' On the other hand, if it falls off from the four parts 1, it falls into the spiral conveyor 3 from the receiving gutter B as shown by the arrow (g), and the other end ju11 (
The paddy sent to b) is discharged as it is, is returned to the bomber 16 from the paddy trough 27, and is deculled again.

On the other hand, brown rice, etc., which is sent to one end side as shown by the arrow (H) by the spiral conveyor 3 in the receiving gutter E, falls into the feeder 3I, and is transferred from the lower opening to -m11 of the downward rotating sorting tube a. The brown rice that is fed inward and mixed with a small amount of paddy is sorted by the downward rotating sorting tube A that rotates as shown by the arrow (S) in the same manner as the sorting tube A. nu)
As shown in the figure, a person fell into the spiral conveyor 3' from the receiving gutter,
As shown by the arrow (R), the brown rice is sent by the spiral conveyor 3', passes through the gutter 33, the flow plate 34, is sorted by the sorting wind, and falls onto the brown rice conveyor 9, and is then transported to the brown rice thrower.
The brown rice-containing paddy is lifted up by 21 and taken out of the machine, and sent into the downward rotating sorting tube a as shown by the arrow (o), passes through the falling plate 32 from the other end (d) and is transferred to the mixed rice conveyor 8.
At the same time, the mixed rice thrower 20 throws the rice up into the supply tank 26 again and sorts it out.

In that case, while engaging the knock 37,
′ along with the chrysanthemum seats 38, 38, the adjustment plate 4.4 can be rotated around the shaft 35.35 to change the inclination, thereby preventing brown rice from falling off from the four parts 1. It is possible to adjust the condition in which people fall onto the receiving troughs B and b, thereby creating moss for sorting and adjusting.

In this way, the present invention has a plurality of rotary sorting tubes each equipped with a receiving gutter for receiving brown rice and having a number of recesses large enough to fit brown rice on the inner peripheral surface, so that the axes thereof are parallel to each other. are arranged above and below to form a rotary grain sorter.
The mixed rice is supplied to the upper sorting tube and is connected to the rice huller so that it can be re-sorted by the lower sorting tube. Since the rotary grain sorters are arranged adjacent to each other in a continuous manner so that the axis of the grain sorter and the axis of the sorting tube are orthogonal to each other, the mixed rice sent from the huller is sorted by the rotary sorting tube and brown rice is sorted. It is possible to receive it in the inner receiving trough and separate it well, and also to sort it sequentially by the upper and lower rotating sorting tubes and to ensure good sorting with good performance. By combining the upper and lower sorting tubes so that their axial directions are orthogonal to each other, the overall width can be made narrower as in the above embodiment, and the overall structure can be made compact so as not to take up much space for installation. It has the feature that it can be easily implemented with a simple structure.

In the example, a rotary grain sorter is mounted above a long wind sorting section, but the present invention is not limited to this example. They may be placed close to each other in parallel, and in short, the present invention connects a plurality of rotary grain sorters so that the axis of the culling roll in the hulling section and the axis of the upper and lower sorting cylinders are perpendicular to each other. They are constructed adjacent to each other.
